I don't see the debug log, it would be helpful to see where the stack overflow happens and to have a backtrace of that. Also: what stack did you increase? In your sdkconfig, the main stack (which calls into the bootloader stuff) only is allocated 3584 bytes. I'd suggest using menuconfig to increase ...

Think it's just an unused subdomain.

I seem to remember some RISC-V (C series) does support SPI-RAM or am I mistaken? Both the ESP32P4 and the ESP32C61 can, but these chips aren't (widely) available yet. If so, I guess I will choose the S series for the foreseeable future and I hope Espressif will keep making/supporting them for some ...

...Okay, thanks for sharing, but did you have a question? In general, yes, if you declare variables inside your functions, it'll use up stack space, and if you didn't allocate enough of that to your task, it'll overflow your stack. Making variables global is one way around that, although normally pe...

That's kinda to be expected. A PEM file is a base64 encoding, in this case likely encoding PKCS information. This encodes way more than simply the private key; there's also identifying information like the serial, common name, maybe name and address of issuer etc. Those things are not necessary for ...

I'm receiving an output voltage of 3.3V. Will it still function properly if I omit the 40MHz crystal? No. The ESP chip will fail to do anything if it can't generate a proper 40MHz sighal. On your schematic:The values of C5 and C6 are way off. 22uF capacitors will kill the oscillation entirely; didn...

Thank you very much! That will save me some parts :) However on the Schematic Checklist i can see they added the there also an Inductor, as reason to stabilize the frequenzy from the crystal. So lets add it and we will see! Thanks :) That's fair, worst case you change it to a 0 ohm resistor in the ...

That will likely negatively affect antenna performance, yes. Sorry, I don't know too much about RF magic to give an indication of how much. Another thing you may want to watch out for that I've had issues with in the past: if you manage to detune your antenna by a lot, you can get issues on WiFi ini...

Yes, the psram is inside the package. No, you cannot add another psram chip externally and expect the amount of accessible memory available to increase, the chip does not support that.

And yes, there is. You need to find some way to call deepSleepFunction 20 seconds after power up. You can either do that manually, by making sure the code path before the call to that function lasts 20 seconds (inserting delays strategically would indeed help there) or you could schedule a timer cal...
